Husband was approached by someone he didn't know last week to see if he was interested in selling his 4WD - they had noted it was a particularly tidy example of the model and some of the features it has are a little hard to come by. After some contemplation (and a quick check of Trademe and with a dealer as to what it might be worth) he allowed them to check it over and test drive it.
They made him an offer. Which was about half what it would be on a dealers yard for and at least a third less than the price we agreed we would contemplate selling it for. When the would be buyer was informed of this he shrugged and said he wasn't willing to pay any more.
I guess if you approach enough strangers eventually you find one that isn't aware of the value of what they have... perhaps
